If a patient has chest pain, he or she needs to register for thoracic surgery or cardiovascular medicine for such symptoms, which may be related to intercostal nerve inflammation or pleural inflammation, internal chest infection, pneumothorax, pleural effusion, and myocardial ischemia, myocardial infarction and other related diseases. The specific condition can be clarified by completing chest X-ray or chest CT, electrocardiogram, cardiac ultrasound and other related examinations. After the specific condition is clarified, more effective measures can be taken for treatment. If the patient completes chest CT and other related examinations and finds that there is infection inside the chest cavity or pleural inflammation, antibiotics can be ordered to provide effective anti-infection treatment, such as levofloxacin hydrochloride or cephalosporins, and penicillin, etc.
